本論文以統合服務描述語言(Unified Service Description Language, USDL)為基礎，提出一個描述智慧家庭服務的擴增服務描述模型。USDL具有商業層面的考量、完善定義的輸入與輸出介面、使用較易開發的低語意語言等數項優點。然而USDL是基於web的服務描述語言，並不具備描述硬體屬性與參數之能力，且智慧家庭服務多數是由硬體裝置所執行，硬體屬性與參數對服務的功能與使用方式有不可忽視的影響力。因此本研究在USDL中加入硬體裝置之概念，並將智慧家庭系統中的服務分類為Web服務、裝置服務與機器人服務，使擴增服務描述模型更適合描述智慧家庭服務。Web服務代表服務是透過網路提供，執行服務的裝置或機器並不在使用者所建立的智慧環境中。裝置服務代表服務是由使用者所擁有的裝置來執行。機器人服務則代表此服務是由家用服務機器人來執行。
本研究同時建立一個測試系統，並設計一個名為吃藥偵測的情境以演示擴充型USDL模型的使用情況。此情境包含一個偵測吃藥行為的裝置服務與自動向指定收件者寄出電子郵件的服務，並利用這兩項服務的服務描述來建立服務之間的溝通與互動。此外本研究亦分別建立網路服務、裝置服務與機器人服務之服務描述範本。

This thesis proposes an extension of the unified service description language (USDL) model in order to better describe smart home services. USDL has several advantages such as a business perspective, low semantic and defined input/output interface. However, the USDL is web-based and does not have the ability to describe hardware device properties, which greatly affect smart home services, as most of these are provided by real devices. Device descriptions should thus be added to the USDL model. In addition, smart home services are further categorized into web services, device services and robot services. The attributes of each service type are defined and discussed in this work.
To further look into the concept of the extended USDL model, a prototype system based on the OSGi middleware is designed and implemented. An example scenario named “medicine intake detection” is built to demonstrate the use of the extended USDL model. The scenario consists of a device service and a web service, and the interoperation between these. It is achieved by using their service descriptions.
The proposed extended USDL model has been evaluated and compared with other service description languages. Based on this comparison, the proposed extended USDL model is better at supporting a smart home system with the ability to abstract heterogeneous hardware devices and hardware interfaces.
